Patent JP-S62174553-A (JP)
Title: Air-fuel ratio control device for engine
Inventor: TAKAHANE TETSUO
IPC: F02D41/14
Filed: 1986-01-28
Abstract: PURPOSE:To enable reduction of unevenness in an air-fuel ratio occurring along with pulsation of intake air, by a method wherein a fuel injection timing is set to a point of time when an actual manifold pressure is coincided with an average pressure. CONSTITUTION:A timing, at which an average pressure of pressures in a manifold in the vicinity of a fuel injection valve 8 detected by a pressure sensor 21 is coincided with an actual manifold pressure, is detected according to the coincidence point detecting flow of a controller 23 by means of the top dead center of a piston 2 serving as a reference point. By equally allotting an injection time to point of times before and after the timing, a timing of fuel injection from a fuel injection valve 2 is set. Since a fuel injection factor during an injection period is a set fuel injection factor at a pressure regulator 16, an amount of fuel injected from a fuel injection valve 8 is a fuel amount accurately responding to a fuel injection pulse width. As a result, an air-fuel ratio is regulated about to a desired value without being influenced by intake air pulsation of an intake air passage 4 along with opening and closing operation of an intake air valve 19.

Title: Charging state detector for battery
Inventor: MUTO FUMIO
IPC: H02J7/00
Filed: 1986-01-29
Abstract: PURPOSE:To accurately detect the charging state of a battery by providing means for measuring the time integration value of the discharge current of a battery and charge-request signal generating means for changing the time integration value in accordance with the quantity of the discharge current to generate a charge-request signal. CONSTITUTION:In a discharge, when a switch 7 is closed, discharge current ii flows from a battery 3 to a load 15 via a shut resistor 5 to develop a voltage across the resistor 5 to be amplified (9) and a voltage V2 proportional to the current i1 is outputted. The voltage V2 is converted (11) to pulse signals P to be counted (13) and the time integration value of the current i1 is measured. Also in a charging at the same time, the time integration value of a charging current i2 is measured (13). Then, when the current i1 is integrated, the signals P proportional to the current i1 are down-counted [23(23-1-23-m)] to be sequentially reduced to zero and switches 25(25-1-25-m) are sequentially closed. On the other hand, since a voltage proportional to the current i1 is inputted to the one terminals of comparators 29(29-1-29-m), when the comparators 29 and the switches 25 corresponding thereto are both turned on, a charging request signal is outputted 35.

Filed: 1978-02-20
Abstract: PURPOSE: To form a timing signal generating circuit which is capable of a simple setting for the pulse position and the pulse duration of the timing signal with reduced number of the circuit component elements by using the AND array for the logic to set the timing position.  
     CONSTITUTION: Binary counter 62 counts the number of the clock signals generated at clock source 61, and the count value is delivered as the binary code. The binary code output is applied to AND array 63 forming the logic array-type AND logic in order to obtain plural output signals which are decoded to plural input signals. The output of array 63 is supplied to J or K input of J-K flip-flops 64W66 and then set or reset by the subsequent clock signals. Thus, timing signals T 1 WT n  are delivered from the set time to the reset time of flip-flops 64W66.

Title: Facsimile equipment
Inventor: SUGIURA AKIRA
IPC: H04N1/405
Filed: 1988-01-27
Abstract: PURPOSE:To transmit a minute change in the density of a picture while keeping the quantity of density information less to be sent to an opposite receiver by setting the step of each density level by taking the standard density distribution of an original to be sent into account. CONSTITUTION:A picture read circuit 1 sends a picture signal 5 being the result of reading the contrast of a transmission original at a multi-value level to a density signal decision circuit 2. A threshold value setting circuit 3 sets which density is to be divided into minute level and which density is to be divided into coarse density level by taking the sent standard original in advance into account and gives a threshold value signal 6 with a value corresponding to each density level to the density signal decision circuit 2. The resolution of the threshold value of the threshold setting circuit 3, taking the standard original handled by the equipment into account, is taken high only to the density level where the density of the original seems to be concentrated and taken lower to other parts so as to send a sufficient gradation difference with respect to the original. Thus, the reception picture with high quality reproducing the intermediate tone of the transmission picture is obtained economically.
